# Which has more momentum, a 3kg object moving at 5m/s or a 4kg object moving at 8m/s?

Mar 7, 2018

${p}_{2} > {p}_{1}$

#### Explanation:

$\text{Momentum = Mass × Velocity}$

Momentum of first object $= \text{3 kg" × "5 m/s" = color(blue)"15 kg m/s}$

Momentum of second object $= \text{4 kg" × "8 m/s" = color(red)"32 kg m/s}$

∴ Momentum of second object > Momentum of first object
